The JMZ1250 is a compact full hydraulic anchor drilling rig specially designed for anchor borehole drilling in small tunnels and confined working spaces. With a compact structure, articulated system, and rotating table design, the rig supports multi-position and multi-angle drilling operations. Equipped with a rotary–percussive hydraulic drifter and powered by a Cummins diesel engine, the JMZ1250 delivers stable torque output and reliable performance. Its small size, flexible operation, and crawler base make it suitable for anchoring construction where space is limited.
Features Introduction
Product Description
The JMZ1250 Compact Full Hydraulic Anchor Drilling Rig is purpose-built for anchoring construction in small tunnels and confined working spaces. With its compact structure, articulated mechanism, and rotating table design, the rig enables flexible multi-position and multi-angle drilling where conventional equipment cannot operate. Equipped with a rotary–percussive hydraulic drifter, it delivers stable torque output and reliable drilling performance across various anchoring conditions.
Powered by a Cummins diesel engine and mounted on a crawler chassis, the JMZ1250 combines strong mobility with precise hydraulic control. Its energy-efficient hydraulic system ensures smooth operation with reduced power consumption, while the compact dimensions and flexible maneuverability make it an ideal solution for tunnel anchoring, slope support, and foundation reinforcement projects in restricted environments.
